PERFOR-ATING lrl'ACHINE.

To all whom it may concern:

Be it known that I, PHILIP J. Frsorrnn, citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inPerforating Machines, of which the following is a specification.

This invention relates to certain new and useful improvements inperforating ma chines and pertains more particularly to that type ofmachines employed to perforate stamps, coupons and checks and the like.

The primary object of the invention is to provide a perforating machinewhich is of the rotary type and which effects simultaneous longitudinaland lateral perfora tion of the sheets, to thereby not only increase theaccuracy of the machine but to also enable same to produce superior workwith an approximate saving of one-half of the time and operating expenseincident to the operation of machines heretofore employed for thepurpose.

Prior to the present invention, the general custom has been to employrotary perforating machines wherein the sheets have been first fedthrough the machine and perforated in one direction and then in a se-o-nd and distinct operation again fed through the machine and furtherperforated in a second direction. Flat bed machines with simultaneouslongitudinal lateral perforating have also heretofore been employed, butsame entail slow hand feeding, which is as objectionable as regard timeand o-per ating expense, as are the two distinct operations of therotary machine.

The present invention therefore aims to overcome tn'e aforementionedobjections and further aims to provide a machine of this type which hasimproved means for mounting the needles in the drums or cylinders andhas still further and other obects, which will be later set forth andmanifested in the course of the following description.

In the drawings Figure 1, is a fragmentary transverse sectional view online 33 of Figure 3 of one of the cylinders, illustrating the manner ofmounting the needles;

Figure 9, is a longitudinal sectional View of one of the cylinders".

in proceeding in a cordance with the present invention, a suitable frame1 is employed having removable heads 2 to permit of easy and convenientaccess to the drums or cylinders in assembly of the latter.

Anv suitable ower means ma' be em 10 ed to drive the machine; forexample an electric motor 3 may be used, which through belt a and pulley5 drives a pinion 6, the latter meshing with a gear 7 keyed on lowershaft 12, the gear 7 in turn meshing with a gear 8 on upper shaft 11.The heads 2 form portions of the bearings for the upper shaft 11 so thatupon removal of the heads, the shaft 11 and the cylinder thereon, may bebodily removed from the frame.

The perforating drums or cylinders 9 and 10 are each composed of aseries of wheels 14 keyed or otherwise rigidly aflixed to the upper andlower shafts 11 and 12 res ectively, so as to rotate therewith andpreferably one-piece bodies which are made or formed of integral lengthsof tubing, as illustrated in, Figure 2 of the drawings. However, asshown in Figure 5 of the drawings, the perforating cylinders may beformed of independent segmental sections 13. the ends of which areaflixed, by suitable fastenings, such as screws, to the wheels 14-, thelatter in all forms of the invention, constituting heads for the drumsor cylinders.

As illustrated in Figure 3, of the drawings, each complete perforatingcylinder is formed of three sections, the end sections each having apair of wheels 14, while the central sectionInot shown, has its ends se-I cured to the adjacentv or inner confronting wheels of the endsections. he perforating cylinders may also be provided with openings A,as shown in Figures 3 and a, the

are

purpose of which is to facilitate the insertion of the needles orpunches in the upper or male drum 9 and to allow the punchings to freelydischarge from the lower or female drum 10.

T he needles or punches B, as depicted in Figure 1, of the drawings,have heads C, the needles being projected through openings providedtherefor in the male drum 9 and having their heads abutting the innercircumference of the drum. As illustrated in Figure 1, the innercircumference of the drum may be provided with grooves G in which theneedle heads are received, although this is not necessary. The heads Cof the needles are engaged by a liner drum 15, which latter functions tohold the needle heads against movement interiorly of the drum, or inother words, acts to retain the needles in place on the drum.

In assembly of the perforating drums, the drums 9 are placed on end, andthe needles inserted from the interiors thereof. In this regard it willbe understood that the needles are arranged in accordance with the typeof perforations which are to be formed in the sheet, i. e., whetherstamps, coupons, or checks are to be perforated. Thus Figures 1 and 2illustrate an arrangement of needles for perforating stamps, but inevent of use of the machine for perforating checks, or coupons or thelike, a variety of arrangements of the needles may be had to fit theparticular requirements. After the needles are arranged as desired, theliner drum 15 is inserted within the outer drum 9, for which purpose theliner drum has a sliding fit within the outer drum. The wheels 14 arethen placed within the ends of the outer drums and abut against the endsof the liner drums, holding the latter against axial movement, andfinally the shaft 11 is inserted through the hubs of the wheels 14 andthe shaft applied to the machine. The female drum 10 is provided withopenings D to receive the punches or needles B during the punching orperforating actions of the needles.

As illustrated in Figures 3 and 6 of the drawings, a suitable feed table16 is provided and upon which the sheets are placed and fed into themachine, while at the rear of the machine, an adjustable delivery table17 is provided, which receives the perforated sheets and conveys thelatter to any desired point or receiver.

The needles are disposed both longitudinally and transversely of thedrums consequently same effect simultaneous perforation of the stampsetc, in a single operation, but a single feeding of the sheets throughthe machine, being required.

It will, of course be understood that the machine is equipped with anycustomary form of guides which control or govern the feeding of thesheets so that the latter will be fed into the machine and engaged bythe needles at predetermined points on the circumference of the drum.

lVhat is claimed is 1. In a perforating machine, a shaft having a pairof spaced wheels thereon, a main perforated tubular drum, the wheelsengaging in the ends of the main drum, so as to support the latter,punches extending through the drum perforations and having headsdisposed interiorly of the drum, and a tubular liner drum in the maindrum engaging the punch heads and having its ends abutting the innerfaces of the wheels so as to be held against axial movement thereby.

2. In a perforating machine, ashaft, two pairs of wheels on the shaft,the wheels of each pair being spaced and the pairs them.- selves beinglikewise spaced, main perforated tubular drums disposed in the spacesbetween the wheels of the pairs and in the space between the pairs andengaged over the peripheries of the pairs of wheels, and over theadjacent wheels of the pairs whereby said adjacent wheels conjointlysupport the said main drum disposed in the space between the pairs ofwheels, punches eX- tending through the drum perforations and havingheads disposed interiorly of the drums, and a liner drum for each maindrum, the liner drums being disposed in the spaces between the wheels ofthe pairs and in the space between the pairs and engaging the punchheads and side faces of the wheels so as to be held against axialmovement by the wheels.

3. In a perforating machine, a shaft hav ing a pair of spaced wheelsthereon, a main perforated tubular drum, the wheels engaging in the endsof the main drum, so

to support the latter, punches extending through the drum perforationsand having heads disposed interiorly of the drum, and a tubular linerdrum in the main drum engaging the punch heads and having its endsabutting the'inner faces of the wheels so as to be held against axialmovement thereby, said main drum having an opening between its ends of'asize to permit the punches to be manually positioned from the interiorthereof.

4. In a perforating machine, a drum hav ing perforations extendingthroughout its length and circumference, heads for the respective endsof the drum, punches extending through. the perforations and havingheads engaging the inner circumference of the drum, and a liner for thedrum engaging the punch heads, said drum being tubular so as to allowthe punches to be selectively positioned through various perforations soas to effect simultaneous perforation of material in differentdirections.

In a perforating machine, a drum having perforations extendingthroughout its length and circumference, heads for the respective endsof the drum punches extending through the perforations and having headsengaging the inner circumference of the drum, and a liner for the drumengaging the punch heads, said drum having an opening of a size topermitthe punches to be selectively positioned through various perforationsfrom the interior of the drum and at points between its ends.

6. A machine for perforating stamps and the like including a drum havingperforations extending throughout its length and circumference, punchesselectively engageable through the perforations, and means to hold thepunches in operative position, the perforations being closely relatedand arranged so as to enable the punches to be set for perforating ofthe stamps simultaneously along each end and side thereof to formtearing lines, and to also permit setting of the punches to perforatesheets for stamps of difi'erent sizes.

In testimony whereof I affix my signature.
